123753-34-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123753-34-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,7,5 and 3 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 123753-34:
(8*1)+(7*2)+(6*3)+(5*7)+(4*5)+(3*3)+(2*3)+(1*4)=114
114 % 10 = 4
So 123753-34-4 is a valid CAS Registry Number.

Palladium-Catalyzed Polyene Cyclizations of Trienyl Triflates
Carpenter, Nancy E.,Kucera, David J.,Overman, Larry E.
, p. 5846 - 5848 (2007/10/02)
Spirotricyclic dienones are conveniently prepared by palladium-catalyzed cyclizations of enol triflate derivatives of 2-dienyl-1,3-cyclohexanediones.The use of chiral (nonracemic) ligands allows assembly of these products with moderate enantioselectivity,
